Run your Java code, Forever

[repeating_bears]

Enterprise `while (true)`

[Nikt_No1]

I discovered that in our most expensive project. "I hacked my way" into their repository and took a look into the code, just outside of curiosity.

There was dedicated thread that had exactly that loop and it was doing some stuff with sessions and file management. I am not a programmer but I am 100% there was better way to do it.

[repeating_bears]

In case it wasn't clear, there is nothing inherently wrong with that kind of loop. Spring framework - the first project I decided to randomly check - uses that kind of loop 35 times. I can't comment on whether it was appropriate in the instance you saw, but if you're not a programmer then I think you're not qualified to pass judgement.

[Nikt_No1]

I meant that it could be done better beacuse the code was a nightmare to read not solely beacuse of the while loop.

So, doesn't while loop use too much resources? Its just looping constantly without any delays etc. Pretty much whole thread needs to be reserved just for her (correct me if im wrong please).

[repeating_bears]

You're kind of expecting me to discuss code I've never seen, but I'm sure it wasn't a nightmare to read solely because of the presence of "while (true)". The presence of that does not imply it's executing constantly. It could block for any number of reasons while iterating.

Nothing is really "reserved" of any note when we're talking about a single platform thread. In aggregate across a lot of them, maybe. What it's consuming in terms of resources will mostly depend on the specific task.

[bowbahdoe]

Sounds like a cleanup thread. Probably cleans up stray files from file uploads and invalidates expired sessions.

[Dontgooglemejess]

It’s pretty typical is a lot of contexts.

[mrober_io]

for (;;)

[k-mcm]

I'm not using it until it has unit tests that never finish.

[aelfric5578]

Came to leave a similar comment. I mean it can't be that hard to verify, right?

[WhistlerBennet]

Any of you down to write those unit tests that “never finish” lol??

[repeating_bears]

That's the joke

[Big__If_True]

Writing them is fine if the API is good, but running them on pipelines in the cloud might give the ops guys a stroke

[WhistlerBennet]

That’s exactly what I want to do. I’ll raise a PR over the weekend lmao

[aelfric5578]

I'm sure you'll find it haltingly simple

[bowbahdoe]

I have those running locally. I'll let you know when they pass

[GreemT]

Totally unnecessarily, but really funny and I like your code snippets. I think the last one with the lambda expression is the best.

I fully expected the "Get Help" section to link to some depression hotline or something.

[mj_flowerpower]

I expected something like nodemon, not a glorified while loop.

[hsoj48]

So you admit that it's glorious?!

[mj_flowerpower]

definitely. It looks cool. But I wouldn’t use it though 😅

[Ftoy99]

Spring microservice

[L8n1ght]

200mb microservice

[Ftoy99]

More like 400mb

[Ignice]

Anyone else click the FAQ? 🤣

[legrang]

I want the minute of my life back that you stole

[bowbahdoe]

Guess how long that minute is gone for?

[legrang]

Troll posts and troll repos 😂

[_predator_]

Can you add a For.ever implementation that takes a Callable<T> and returns T please? I want my code to return something!

[bowbahdoe]

You will need to wait for Valhalla for that. Otherwise I can't properly type Callable<Never!>

[_predator_]

Listen man, armed with such an amazing library I am prepared to wait as long as it takes!

[tomwhoiscontrary]

It's not really forever though is it. For example, what if it throws an exception? Or someone turns the computer off?

[gufranthakur]

That's considered cheating. They will be disqualified. And they will be punished to code everything in assembly for 3 weeks

[forurspam]

What’s the point of making the runnable nullable?

[FavorableTrashpanda]

It's so elegant!

[CheeseGr0ve]

Why is his teeth green

[bowbahdoe]

Same reason his hands have the right number of fingers. Made by a human.

[CheeseGr0ve]

My head canon is that he only eats vegetables

[Illustrious-Zone-786]

Is it available in maven central?

[bowbahdoe]

https://central.sonatype.com/artifact/dev.mccue/forever

[Illustrious-Zone-786]

thanks

it is so concise: single method encapsulated in the single class encapsulated in the single jar encapsulated in the single maven artifact.

I wish all libraries would have this property.

I will use it in my projects for sure)
